Question: An elderly patient had a 1.4-centimeter skin tear on his left thigh. The dermatologist cleaned the tear and used Dermabond to repair it. How should I code this encounter?

Answer: Although CPT specifically mentions closure with tissue adhesives as a method of repair, correct code use depends on the patient's insurer.
 
When the dermatologist performs a single-layer closure on a patient, private carriers and Medicare have different expectations of the coder.
 
If Medicare insures the patient, you should report G0168 (Wound closure utilizing tissue adhesive[s] only) for the encounter.
 
But if the patient has a non-Medicare insurer, you'll need to select a code from the series for simple laceration repairs, depending on the length of the repair. In this instance, you would report 12001 (Simple repair of superficial wounds of scalp, neck, axillae, external genitalia, trunk and/or extremities [including hands and feet]; 2.5 cm or less) on the claim for a non-Medicare carrier.
 
Remember that successful wound care claims document the exact measurement of the repair. Make sure your dermatologist documents wound length, in centimeters, in her notes.
